Three things I love: chocolate (preferably in chip form), blondies, and sourdough. So honestly this recipe is heaven to me. Actually, let’s add a fourth thing: I love being able to use up sourdough starter discard in recipes.
It makes me really happy to see how many people are making sourdough starters during this period of quarantine. And it makes me even happier to see people looking for recipes to use up starter discard instead of just throwing it in the trash. Food waste is dumb.
If you’re looking for a new and unique recipe to use up that sourdough starter, keep reading because I have the best recipe for you.
These blondies are thick, buttery, and full of melty chocolate chips. And on top of all that, they’ve got just a hint of a sourdough taste, which adds a whole new depth of flavor.
But my favorite thing about these blondies is the texture. They’re light and fluffy, almost like a mix between a typical chewy blondie and a slice of buttery, fluffy cake. So good.
How to make Chocolate Chip Sourdough Blondies
These blondies are super easy to throw together and baked to perfection in under 30 minutes. The only slightly tricky part is making sure that the sourdough starter is completely incorporated, because otherwise they’ll bake unevenly and have some doughy spots throughout. Once you add the sourdough starter, be sure to mix the batter for a full 5 minutes so everything gets fully blended together.
